The trunk was in remarkably good condition and kept that way by the previous owner. He sprayed the whole trunk with a rust preventative or undercoating. It took a lot of cleaning solvent to remove all of the tarry coats and with the exception of some minor surface rust around one of the drain holes; everything was rust free. I wiped down everything with naptha and sprayed it with a left over can of 620 medium copper that matched fairly well.
